warp-contracts-plugin-deploy-testnpm
Advisory published Updated
warp-contracts-plugin-deploy-test is a confirmed malicious npm package (MAL-2026-4712) that steals credentials and exfiltrates sensitive data (malicious version 3.0.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in warp-contracts-plugin-deploy-test (npm)
What this malware does
Package name warp-contracts-plugin-deploy-test mimics the legitimate warp-contracts-plugin-deploy and copies its public API surface (lib/cjs/index.js re-exports DeployPlugin, CreateContractImpl, SourceImpl, Arweave/Ethereum signers identical to the genuine package). package.json declares "preinstall": "./bin/install-deps" where bin/install-deps is a 976,568-byte packed Linux ELF binary (sha256 36abd242ddaa27f0160c539377a0e92cf781c1695137850acc87e3892b436d36). The package self-describes as a TypeScript Warp Contracts deploy plugin — there is no native source tree, no node-gyp/binding.gyp, no documented purpose for shipping a Linux ELF helper. Readable strings in the binary (LIBBPF, PTRACE, NETLINK_DIAG, HTTP/1.1, https://, USERPROFILE) are inconsistent with any deploy-plugin function and consistent with a host-implant payload. On npm install, the binary runs with the installer's privileges, executing attacker-supplied compiled code that the scanner cannot inspect.
This package was compromised as part of the IronWorm campaign. This campaign executes a malicious binary payload during installation via a preinstall hook. The payload is a Rust-built infostealer that targets developer environments, scanning for and harvesting credentials related to cloud providers, object storage, databases, source-control, package registries, and AI developer tools. It also targets cryptocurrency wallets, specifically injecting a malicious JavaScript hook into the Exodus desktop wallet to capture passwords and recovery phrases. Furthermore, the malware exhibits worm-like behavior by stealing GitHub and NPM credentials to push malicious updates to the victim's repositories and publish trojanized packages, and it uses an eBPF-based kernel rootkit to hide its processes and network connections on Linux systems.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for warp-contracts-plugin-deploy-test (version 3.0.1).
If you installed it — respond
warp-contracts-plugin-deploy-test is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If warp-contracts-plugin-deploy-test was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks warp-contracts-plugin-deploy-test-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
